摘要

mccraly涂层为涡轮叶片提供有效的高温保护，防止氧化和腐蚀。然而，在使用过程中不可避免的热-机械耦合对涂层的抗氧化性产生了重大影响，其内部机制尚不清楚。研究了NiCrAlY涂层/镍基单晶高温合金体系在有/无热-机械耦合条件下的氧化行为。结果表明，在有应力和无应力的情况下，试样的氧化鳞明显不同。热-机械耦合促进了较厚的、保护性较差的尖晶石氧化物和较薄的保护性氧化铝层的形成。值得注意的是，仅在热-机械耦合试样表面检测到富w - y的Y2WO6氧化物。热-机械耦合效应加剧了NiCrAlY涂层的内部氧化/氮化，削弱了氧化皮的保护能力。

Thermo-mechanical coupling effects on the high-temperature oxidation behavior of a NiCrAlY-coated single-crystal superalloy

MCrAlY coatings provide effective high-temperature protection against oxidation and corrosion for turbine blades. However, the inevitable thermo-mechanical coupling during service has a significant impact on the oxidation resistance of the coating, and the internal mechanism remains unclear. This study investigated the oxidation behavior of the NiCrAlY coating/nickel-based single-crystal superalloy system under conditions with/without applied thermo-mechanical coupling. The results indicate that the specimens with/without stress developed markedly different oxide scales. Thermo-mechanical coupling promoted the formation of thicker, poorly protective spinel oxides and a thinner protective alumina layer. Notably, W-Y-rich Y₂WO₆ oxides were exclusively detected on the surface of thermo-mechanical coupling specimens. The thermo-mechanical coupling effect aggravated the internal oxidation/nitridation of the NiCrAlY coating and weakened the protective capability of the oxide scale.

期刊介绍： Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies. This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
